I'm pretty well convinced that the exclamation point, which is the implicitly-unwrap-optional operator, in Swift is just a giant sign that says "I LOVE IT WHEN MY APP CRASHES!"
Other than example code where you're going to be passing literals to things, I can't see any reason to use it.

You know... if writing an app once for all platforms really was the best solution for making really good apps, then it seems to me that this is what the company that just hired me would be doing.
Xamarin shows a lot of promise though, although I always felt a little wary about it. I can never shake the feeling it must be missing native options somewhere
Xamarin shakes some of them, but it's not exactly as they preach. You still need a Mac and Windows 8 and so an so to do the whole thing. I'd say Android is the only OS which you can make something for it using Xamarin straight away
@nhgrif Yeah. I am not gonna argue that each one of the separately developed ones going to ace and surely be better than something which is developed in a One-for-all env. but you know depends what you need
But they don't develop it once. There's a Ruby developer who does the backend, an iOS developer who does the iOS app, an Android developer who does the Android app, etc.
@JeroenVannevel Yeah. It's not too bad. I borrowed my bosses' old mac to start with but I mean everybody installs Xamarin thinking all I need is this env and i will have an app for Windows, Android and Mac in no time all tested in an emulators :)
@Mehrad In my current job, I am an iOS/.NET/SQL developer. I have 3 apps on the iOS app store. In June, I am starting a new job as a senior iOS developer. I'm completely aware of the entirety of iOS development.
Where I work, they have a build server. Whenever you push a commit, it automatically builds the app on a zillion different actual devices and then runs a really in-depth UI test on all of the devices.
I think for iOS they have every iOS device going back to the 4s. I don't know (or necessarily particularly care) what they have for Android. Android is kind of a pain to keep up with all the different devices.
it's a luxury to have an access to zillion different devices though, cuz you still need to pay an arm and a leg to get it tested on 100 devices with Xamarin.
Yeah. There's "a zillion" at the build server. But there's also a selection of different devices I'll have immediate access to for actually playing around and testing.
Plus, they have an enterprise account, so I think that's unlimited Apple device registrations.
@nhgrif pain is just an starter. There is a problem with Android called different APIs :) and if you're thinking backward and forward compatibility, forget about it
I think I took level 16 in the project creation screen, but I'm using some v4 support libraries. No clue why they decided on a different versioning system for that
@JeroenVannevel When I started, i hoped into Android room and asked the prime question of which API should I start cuz Bluetooth doesn't support one version higher and one lower of itself and they all laughed and said yeah yeah, we all been there :D
The sequence of Fibonacci numbers is defined as F1 = 1, Fn = Fn−2 +
Fn−1. It has been conjectured that for any Fibonacci number F, F2 + 41
is composite.
... [T]ask is to either prove the conjecture to be true or find a
counter-example that demonstrates it is false.

I am currently in an intro C++ programming class. We have an assignment where we have to convert a dollar and cents amount, say $192.89, to bills and coins using the least amount of both. Below is the program I have written and everything works, however, when I enter a value $XXX.89 it always tru...
Downvote an answer, explain in a comment the problem with the answer, answerer replies "I suggest you try it and remove your erroneous vote." when... if they'd just try their own answer themselves, they'd see that they're wrong.
@nhgrif Just because someone has 29k reputation, doesn't make them exempt from stupidity, also, he may have points for Java or something and be branching into Swift.
